When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the main tool for assessing the degree of obesity. It is calculated by dividing body weight (kg) by height squared (m²). Surgery is usually justified with a BMI above 40, or above 35 with serious related conditions. In some cases surgery is considered at lower values too — if non-surgical approaches have failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Previous tries at losing weight with ordinary methods have failed
Why don't diets and exercise work for everyone?
It is common to try various diets and exercise for years while the body resists — slower metabolism, stronger appetite, returning weight. When it becomes evident that diet changes and medication by themselves cannot fundamentally help, bariatric surgery becomes the only effective solution.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
The operation involves removing most of the stomach and turning it into a narrow tube. As a result portions shrink a lot and the hunger hormone ghrelin falls, so the patient reaches fullness sooner and eats less.
Effectiveness: the method fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: results are less lasting than with bypass surgery. Weight can return if the diet is not kept, especially with high-calorie drinks and liquid foods.
Roux-en-Y gastric bypass
Using the top of the stomach, the surgeon creates a small 50–70 ml pouch joined directly to the small intestine. This limits intake and reduces the calories absorbed by cutting short the journey of food through the gut.
Effectiveness: the operation counts as the “gold standard” for BMI above 45–50 with type 2 diabetes; 75–85% of excess weight is lost.
Specifics: the result endures better than with alternative bariatric methods. Associated diabetes and hypertension frequently go into remission. Lifelong vitamin and mineral supplements are required because the digestive anatomy changes.
Mini gastric bypass (MGB)
An upgraded take on the classic bypass. In contrast to the standard method, only a single connection (anastomosis) is made between the small stomach and the small intestine. Being simpler, the technique is easier on the patient and shortens recovery.
Effectiveness: on par with the classic Roux-en-Y bypass — patients shed up to 75–80% of excess weight.
Specifics: less time in surgery and a faster recovery. Technically the procedure is reversible, though the single anastomosis brings a risk of bile reflux.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combination technique that draws on the benefits of both sleeve gastrectomy and intestinal bypass. In two stages, the stomach is first converted into a narrow tube and the small intestine is then rerouted to exclude its greater part from active digestion.
Effectiveness: counted among the most powerful bariatric operations — 80–90% excess weight loss with a durable result.
Specifics: a smaller stomach curbs appetite because the ghrelin-producing zone is removed, and sending food past part of the intestine limits calorie absorption. It suits super obesity (BMI over 50), severe type 2 diabetes, or a second stage after a sleeve that did not work.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
The approach to obesity at City Medical Centre is comprehensive. Following an initial examination, a personal diagnostic program — lab and instrumental — is drawn up for each patient to detect every disorder in the body.
A method matched to your goal
The surgical method is chosen by our doctors on an individual basis. They first review your health, your weight history and related conditions, then offer the surgical treatment that suits you best.
Support that stays in touch
After surgery the City Medical Centre team continues to support you. Throughout year one, specialists track weight loss, review your tests and answer all your questions on diet and recovery.
Fast recovery
Laparoscopic bariatric operations at City Medical Centre make recovery far shorter. Most patients are moving on day one and resume their normal life within a week.
Full diagnostics on site
No shuttling between clinics. Your full work-up happens at our centre, from our own lab to ultrasound and gastroscopy. Preparation is quick, there are no queues, and it is all in one building.
Recovery after bariatric surgery
Recovery depends heavily on the individual, but minimally invasive laparoscopic methods keep rehabilitation as short as possible.
Duration
The patient is kept under clinic observation for 1 to 5 days, depending on the scale of surgery and related conditions.
Activity
Sitting up, standing and drinking are allowed in the first hours after surgery.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
You can resume working 7–14 days after surgery, based on how physically demanding your job is.
Restrictions
For the first weeks, no bathhouse, sauna or intense physical exercise.
Diet
You follow a staged diet for 1–2 months, going from liquid to solid food as the stomach adapts.
Pace
On average, patients who follow the specialists' advice lose 10% of excess weight a month.
Stabilization
The final result is seen after 1.5–2 years. In that time the patient builds stable eating habits that keep the weight from returning.
Important! Specialists from City Medical Centre supervise recovery and provide psychological and medical support at each weight-loss stage.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
Many mix them up, but they pursue fundamentally different goals. Bariatric surgery medically treats obesity and related diseases by changing how the digestive tract functions, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the external contours of the body; it does not treat obesity or influence metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
We apply modern laparoscopic technique, operating through 4 small punctures of 5 to 15 mm. Thanks to cosmetic sutures, the marks are almost invisible once they heal.
What diet do I need to follow?
Your meals progress in stages: liquid food, soft food, then solid. The stress is on protein and on reducing high-calorie, fatty food.
What types of bariatric surgery are there?
There are four main types of bariatric surgery at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. BMI, related conditions and the patient's goals guide the individual choice of method.
Can I plan a pregnancy after surgery?
Pregnancy after bariatric surgery is possible, though doctors recommend waiting at least 12–18 months. In that time the body stabilizes, weight reaches its target and nutritional status returns to normal.
Do I need to take vitamins after surgery?
Yes, vitamins are essential after bariatric surgery. As digestive anatomy changes, the body absorbs certain nutrients less well, so regular vitamin and mineral supplements become a lasting part of the patient's life.
Can the weight come back?
Although weight regain after bariatric surgery is possible, it is very unlikely if you follow the doctor's advice. Proper eating, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are key.

Bariatric surgery in Santiago: what you should know
Mini gastric bypass is an improved version of the classic operation with a single connection between the small stomach and the intestine. The technique is simpler, recovery shorter, and weight loss reaches 75–80% of excess weight. It is technically reversible, but bile reflux is a possible risk. For people from Santiago, the surgeon explains such trade-offs before any decision.
Recovery is short thanks to the minimally invasive technique, and absorbable sutures dissolve on their own. Office work is usually resumed after 2–4 weeks and physical work after about 1.5 months; swimming is allowed after 30 days, with other exercise added gradually. For the first weeks, no sauna or intense training. Santiago residents get the same step-by-step guidance from the team.
Before spending on another diet, get a professional assessment. A short no-cost talk with the surgeon, about a quarter of an hour, shows whether your BMI and related conditions justify surgery. If they do, one package takes you through tests, the operation, care in the ward and follow-up, with the weight loss result set in a contract. Residents of Santiago can apply online.
